Abstract
A composite cooking machine includes a plurality of switches which are connected in series with a plurality of component cooking machines, between a circuit breaker in a home and the component cooking machines, respectively, to selectively supply power to the component cooking machines. A control unit of the composite cooking machine controls the switches so as to supply the power to only one of the component cooking machines, without responding to a key signal for another one of the component cooking machines, where a cooking operation performed by the one component cooking machine has not been completed. Therefore, the composite cooking machine does not allow simultaneous operations of the component cooking machines, and prevents unnecessary operations of the circuit breaker. Accordingly, the reliability of the composite cooking machine is improved.

Where it is determined that the cooking operation performed by the secondcomponent cooking machine 300 has not been completed, thecontrol unit 450 performs the cooking operation according to a key signal corresponding to the secondcomponent cooking machine 300 inoperation 94. At this time, since thecontrol unit 450 does not respond to the key signal input in theoperation 90, for example, a key signal corresponding to the firstcomponent cooking machine 200, the first switch SW1 is maintained at its turned-off state, and power is not supplied to the firstcomponent cooking machine 200. - Where it is determined that the cooking operation performed by the second
component cooking machine 300 has been completed in theoperation 92, thecontrol unit 450 turns off the second switch SW2 inoperation 96. Thereafter, thecontrol unit 450 executes theoperation 84 to perform a cooking operation by either one of the first and secondcomponent cooking machines - As described above, the present invention provides a composite cooking machine which supplies power to only one of component cooking machines, without responding to a key signal for the other component cooking machines(s), where a cooking operation performed by the one component cooking machine is not completed. Therefore, the composite cooking machine of the present invention does not allow simultaneous operations of a plurality of component cooking machines, thus preventing unnecessary operations of a circuit breaker, and consequently increasing the reliability of the composite cooking machine.
